RUDOLPH F. EMMERICH AND FREDERICK VONDERLEHR, OF NEW YORK, N. Y.

BRONZlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 613,857, dated November 8, 1898. Application filed May 6, 1898. Serial No. 679,888. (No model.)

To all whom it may concern.-

Be it known that we, RUDOLPH F. EMMER- ICE and FREDERICK VONDERLEHR, citizens of the United States, and residents of New York, in the county and State of New York, have invented new and useful Improvements in Bronzing-Machines, of which the following is a specification.

This invention relates to certain improvements in bronzing-machines in which mechanism is provided for accurately determining the amount of bronze to be distributed onto the sheet being treated and also in which simple mechanism under the control of the'shaft of the sheet carrier or cylinder is provided for reciprocating the bronzing-pad carriage and one of the superfiuous-bronze-removing rolls while the said pads are being rotated.

A practical embodiment of our invention is represented in the accompanying drawings, in which I Figure 1 is a view of the left-hand side of the machine. Fig. 2 is a vertical central section from front to rear through the same, representing such portions of the machine only as are necessary to the complete understanding of the improvements. Fig. 3 is an enlarged view of the divided cam for controlling the movement of the bronze-distributing roll, the members being adjusted so as to give the slowest movement to the said bronzedistributing roll, thereby adapting it for use in connection with long sheets. Fig. 4: is a vertical central section through the samein the plane of the line 4 4 of Fig. 3. Fig. 5 is a section in the plane of the line 5 5 of Fig. 4, looking toward the movable member of the cam; and Fig. 6 represents an outer View of the cam with the members adjusted in position to give the quickest movement to the bronze distributing roll, adapting it for use in connection with short sheets.

A A represent the side frames of the machine, in which is j ournaled the revolving paper-carrying cylinder B. A feed board or table 0 is mounted upon forward extensions of the side frames A A,wit-h its rear edge resting in closest proximity to the cylinder near its top. This feed-table is adapted to support sheets of paper or other material which it is intended to treat with the bronzing process.

The main drive-shaft is denoted by D, and

it .may be driven in any suitable manner. (Not shown.) The drive-shaft D is provided with a spur-pinion d,-which intermeshes with a spur-gear I), carried by the shaft 1) of the rotary cylinder B.

The cylinder B is provided at its periphery with a suitable paper-gripper E. This gripper may be caused to engage the paper, draw it through the machine, and disengage it by any suitable means, which means are not shown herein, as they form no part of the present invention.

A bronze-distributing roller F is located in proximity to the face ofthe paper-carrying cylinder near the rear edge of the feed-table. Above this roll F is located a receptacle G, having an opening 9 in its bottom for distributing bronze onto the face of the roll.

The means for controlling the amount of rotation, the speed of rotation, and the starting and stopping of the bronze-distributing roll F to adapt it for use in connection with sheets of varying lengths is as follows: A double or divided peripheral cam is mounted upon the end of the shaft 1), the member H being stationary with respect to said shaft and the member H being capable of a rotary adjustment thereon. The cam member H gradually increases in diameter for about three-fourths of its circumference, and the movable cam member H gradually increases in diameter for about one-third of its periphery, the outermost and innermost points of the tracks upon the said cam members being practically the same distance from the center of the shaft 1). The movable cam member H is provided with an elongated concentric groove h, within which is located a clampingbolt 72., extending from the member H. By this means two members may be clamped in any desired rotary adjustment relatively to each other.

A two-armed rocking lever I is pivoted at 'i to the side frame A. The downwardly-extended arm 9; of the lever is provided with a lug i which is adapted to travel along the peripheries of the cam members H H. This lug may be provided with an antifrictionroller i if so desired. The upper arm 1' is provided with an elongated groove F. A second rocking lever J is mounted to rock freely on the shaft f of the distributing-roll F. The

downwardly-extended arm j is provided wit-h an elongated groove 3'. The upnvardlyextended arm j is provided with a pawl j", which is in position to engage a ratchet-wheel 5 f, mounted to rotate with the shaft f of the distributing-roll. The arms 2 and j of the levers I J may be adjustably engaged with each other, so as to increase or decrease the amount of rotation of the roll F as the arms are rocked bya clamping device j, arranged to be adjusted along the elongated grooves j. To prevent the lever I being further rocked after it leaves the highest point upon the cam member II when the cam member is arranged to cause the lever to rock to the limit of its movement at any point before it would naturally be caused to rock by the member II,we provide a ban d-spring hflwhich is secured at one end to a block 7L3, located at the outermost point on the member II, the free end of the spring being caused to pass through the abrupt portion of the cam member II into the interior of the said member just beneath its periphery. An operatinghandle it is provided with a cam h, which cam is adapted to engage the long arm 71 of a lever 7L7, so that when the knob is turned to cause the cam to depress the said arm the short arm 7&8 of the said lever will be caused to grip the spring 7L2 and hold it rigidly in position.

The outer face of the cam member II may be provided with a suitable scale along which the abrupt portion of the periphery of the cam member H is caused to pass, so that the two members may be quickly and accurately adjusted with respect to each other and in accordance with the length of the sheet of paper or other material which is to be treated.

An auxiliaryshaft K is mounted in the side frames A A, which shaft is provided with a gear 7t, which intermeshes with a gear d on the drive-shaft D. A plurality of rotary pads Z are mounted in a carriage L, located a short distance to the rear of the bronze-distributin g roll F, the shaft Z of which is provided with a pulley P, which is driven by a belt Z leading to a pulley 7c on the shaft K. This rotary shaft Z is connected with the shank of the pads Z, so that the rotary movements of the shaft causes the said pads to also rotate. Upper and lower supertluous-bronze-removing rolls M N are located to the rear of the bronzing mechanism, with their peripheries in proximity to the periphery of the papercarrying roll 13. The upper roll M is provided with a pulley m, which is driven by a belt m, leading to the pulley on the shaft K. The lower roll Nis provided with.a pulley n, which is driven by a belt a, leading to a pulley 70 on the shaft K.

The bronzing-pad carriage is reciprocated laterally as the pads are being rotated by means of a rocking lever O, pivoted at 0 on the side frame A and having the free ends of its upper arm 0 secured to the said carriage L and the free end of its lower arm 0 engaged with a peripheral cam-groove p in a cam P, carried by the shaft 1) of the papercarrying cylinder. In the present instance the cam 1 is connected on the shaft 1) by a suitable feather-and-groove connection 11, and the cam member II is secured to said cam P by a suitable set-screw 7t".

One of the superfluous-bronze-removing rolls, in the present instance the upper roll M, is reciprocated simultaneously with its rotary movement by means of a rocking lever Q, pivoted at q 011 the side frame A, the said lever having its arm (1 connected with the shaft m of the said roll and its other arm 1 engaged by a lug or pin 0 on the upper arm 0 of the lever O. B y this arrangement a single cam on the shaft Z) serves to reciprocate bot-h the bronzing-pad carriage and the superfluous-bronze-removing roll.

Suitable shelves or partitions R S may be provided beneath the rolls M N for receiving the superfluous bronze as it is brushed from the paper being treated. The bronze thus collected may then be removed in any suitable manner.

It will be seen that the speed of rotation and the amount of rotation of the bronze-distributin g roll F can be accurately and quickly adjusted to suit the varying requirements, thereby correctly determining the amount of bronze which may be applied to the sheet undergoing the bronzing process.

That we claim is- 1. In a bronzing-machine, a rotary sheetcarrying cylinder,a bronze-distributing roller and mechanism connecting the cylinder and the roller comprising means for adjusting the speed of the roller and means for adjusting the amount of rotation of the roller to adapt it for use in connection with different lengths of sheets, substantially as set forth.
